Default i found 2 resonant freqs for my car:( ???

i found 2 resonant freqs.1 was around 44hz and 1 more at 65hz.which of these should i use as resonance?

p.s. i made 2 tests

1)1 ported xxx15 at 31hz
2)the same xxx15 at same box but this time sealed(i muted the vent)

the peaks was almost the same around 44hz but at 65hz were identical!!!

i assume he is doing spl competition -- anyway, i would shoot for the higher res freq -- easier to make a huge port bc the length wont need to be as long
